What does DEXA measure?

  • Body fat results:

Body composition scans with DEXA / DXA provides precise and accurate data on total body fat percentage, total fat mass and fat-free mass. Most importantly, what is unique about DEXA body composition technology is that it provides regional body fat results (trunk, arms, legs, pelvis and android/gynoid regions). For instance, DEXA scans can give a precise measurement of visceral fat / abdominal fat. · Abdominal, or visceral, fat is of particular concern because it's a key player in a variety of health problems — much more so than subcutaneous fat, the kind you can grasp with your hand. Visceral fat, on the other hand, lies out of reach, deep within the abdominal cavity, where it pads the spaces between our abdominal organs. · Visceral fat has been linked to metabolic disturbances and increased risk for cardiovascular disease and type 2 diabetes. In women, it is also associated with breast cancer and the need for gallbladder surgery.

  • Bone Density (bone mineral density - BMD)

Please note that DEXA scans do subject you to small amounts of radiation. A whole-body scan produces a level of radiation equivalent to flying by airplane from New York to California.
